Abstract
Abstract A surgical tool of the type comprising a first stationary jaw member and a second movable jaw member adapted for pivotal movement towards and away from the first stationary jaw member, wherein the second movable jaw member is attached to the first stationary jaw member by a first arcuate lug and groove arrangement, and the second movable jaw member is also attached to a coupling member by a second lug and groove arrangement, in order that when the coupling member is moved in a first direction relative to the first stationary jaw member, the second movable jaw member will open away from the first stationary jaw member, and when the coupling member is moved in a second opposite direction relative to the first stationary jaw member, the second movable jaw member will close towards the first stationary jaw member. The invention may take the form of surgical punches or surgical forceps. A novel locking means is provided for the surgical forceps.
